* Sandbox includes a limited personal AI extraction allowance, and Deep verification runs draw on it. Advanced models and the catalog copilot require Pro.

† Pro includes 100 Deep verification runs a month as a soft allowance; a copilot sync with your pricing page uses one. Contact support if you need more capacity before the monthly reset.

SSO, residency, and SLA terms are scoped in your order form.

Every tier includes everything in the tier before it.

These plans are published on PairRail itself.

We publish our own prices as an Atlas catalog, the way you would publish yours. Any buying agent can read them without a key.

Browsing is free. Only real work counts toward your queries.

Agents and crawlers can read your catalog without using your quota. Only calls that compute something for you, such as pricing calculations and readiness checks, count.

What counts as a query

Plans, queries and billing

More answers in the full FAQ, or email support@pairrail.com.

What’s included in Sandbox vs Pro?

The cards above are the full list. Sandbox is free: your public pricing is live on MCP with a hard query cap, and quotes run as a marked rehearsal. Pro is the live commerce plan: all five protocols, live quotes and billing handoff, included volume with overage, and the seats and keys on the Pro card.

What counts as a query?

Agents can find you for free; only real work counts against your quota:

Browsing is free. catalog_browse and REST /v1/public/catalog are edge-cached and never use your query quota. Crawlers and agents exploring your products never cost you credits.
Compute counts. catalog_discover, pricing_calculate, readiness_inspect and authenticated agent operations count toward your plan’s included monthly volume, and only when they succeed. Access requests, failed calls and retries that replay an earlier quote are free.
Protocol overhead never counts. MCP handshakes (initialize, tools/list, tools/listChanged, ping), static discovery files (/llms.txt, /.well-known/*, /openapi.yaml) and health probes never use quota.

Sandbox traffic (1,000/month, hard-capped) is metered separately and does not use Pro included volume after you upgrade.

How does overage work on Pro?

Pro includes 25,000 queries per month. After that, overage is $2 per 1,000 queries ($0.002 per query), billed through our payment partner at the end of your billing cycle.

Unauthenticated public traffic never creates overage and does not use your included queries. It has its own monthly allowance of the same size; once that is used, anonymous calls pause with a 429 response. Only agents with a validated machine key use your included queries and overage capacity.

Can I pause agent traffic or turn off anonymous pricing?

Yes, on every plan. Your workspace has a seller kill switch that pauses all agent traffic (public and keyed) immediately, a toggle for anonymous pricing, an optional daily anonymous query cap, and per-buyer key expiry. Every kill-switch change is recorded in your audit log.

Can I see a breakdown of my query usage by type?

Yes. Your workspace billing panel shows queries grouped by category: Catalog Browse, Catalog Discover, Indicative Pricing, Readiness, Access Requests and Agent (authenticated). You see which operation type is driving volume before you reach overage, so there are no surprises at billing time.

Do I need a credit card for Sandbox?

No. Sign in with Google, GitHub or a 6-digit email code to get an isolated Sandbox workspace and start extracting and scoring readiness without a card. You only pay when you upgrade to Pro.

Can I switch between monthly and yearly?

Yes. Choose monthly or yearly at checkout. To switch later, use the Subscription panel in your workspace. It shows what you will pay before you confirm.

Monthly to yearly takes effect right away. You pay the yearly price minus a credit for the unused part of your current month, and your yearly term starts that day.
Yearly to monthly takes effect at the end of your paid year. Nothing is charged until then, and there is no partial refund for the rest of the year. You can undo it before that date.

Switching is not available during a free period or while renewal is cancelled. For help, email support@pairrail.com.

Who processes payment for my subscription, and can I cancel?

Checkout and subscription billing for your Atlas plan run through our payment partner. You can manage or cancel the subscription from the billing portal linked to your account, or email support@pairrail.com.

Who bills my customers?

You do, through your existing billing, and tax filing stays with you. PairRail takes no per-transaction cut. How the handoff works.

Is Enterprise self-serve?

No. Enterprise is contract paper: custom volume, a signed DPA on request, and questionnaires. SSO, residency and SLA terms are scoped in your order form. Sandbox and Pro use Google, GitHub or email OTP. Email support@pairrail.com.
